Abstract
As regards the super cooling phenomena which is important matter in encapsulated ice system, the system efficient suffering from the super cooling release of water was estimated and the performance of release reagent was determined. The following conclusions were reached.
(1) It was clear that the COP of heat storing of the system fell by 3% with decreasing release temperature by 1 degree centigrade.
(2) As a result of determinations about release reagents, Xanthomonas campestris (ice nuclei bacteria) was very effective in release the super cooling state, and the performance was maintained in continuous application of freezing and melting.
